JOURNAL BOX.

To all whom it may concern:

Be it known that I, FRED C. CosEo, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented new and useful Improvements in Journal Boxes, of which the following is a specification.

The present invention relates to certain new and useful improvements in journal boxes for the axles of locomotives of the class adapted to use in coal mines for hauling cars of coal from the mine.

To meet the haulage requirements of coal mines there has been developed a type of locomotive of extremely rigid construction,

adapted to Withstand the severe service conditions obtaining in the dark and tortuous passages of the mine. Owing to the irregular surface and alignment of mine tracks,

and to the prevalence of curves of extremely short radius, the axles of such locomotives are subjected to excessive end thrust which tends to the rapid destruction of the wheels and journal boxes.

It is the especial object of this invention to provide an improved axle journal box especially adapted to the severe service con ditions above described, provided with improved end thrust bearing devices having 0 extreme wear resisting qualities, and adapted to be conveniently and expeditiously renewed.

The means by which I attain this object are fully set forth in the following specifi- 5 cation, and illustrated in the accompanying drawing, of which,

Fig. 1 is a side elevation of a locomotive of the class described equipped with the devices of my invention.

' Fig. 2 is a fragmentary view showing one of the boxes illustrated in Fig. 1 on an enlarged scale.

Fig. 3 is a sectional View taken along the line IIIIII of Fig. 1 on a scale still. further enlarged.

Fig. 4: is a perspective view of the oil box which constitutes the part of the journal box illustrated in Figs. 1 and 2.

Fig. 5 is a perspective view of the end thrust bearing plate adapted to be attached to the oil box to engage the hub of the wheel and thereby limit longitudinal movement of the axlev relative to the side frame of the locomotive.

Like numerals refer to similar parts in the several figures.

To meet the service conditions existing 7 in coal mines there has. been developed a type of locomotive having side frames 1 formed of heavy steel plates joined together by suitable cross members to form a rigid framework. The electric motors, andother operative parts of the mechanism, are enclosed Within this framework which is especially adapted to protect them from injury by the fall of material from the roof of the mine. Current for the actuation of the motors of the locomotive is derived from j the trolley wire 2 through the trolley pole 3 in the manner well understood in the art,

and controlling mechanism 4 adapted to control the actuation of the locomotive-is positioned convenient to the hand of the 7 in the usual manner, and these axles are ournal bearings 8 adjacent provided with said wheels, upon which bear the antifriction metal linings 9 of the journal boxes 10. As the journal boxes 10 are alike a description of one will apply to all.

The journal box 10 is adapted to slide vertically in a recess 11 formed in the lower edge of the side frame 1, and flanges 12 formed in the metal of the side frame, engage the edges of the journal box 10 to prevent its accidental displacement transversely of the locomotive. Formed in the journal box 10 are spring pockets 13, and compression springs 14 seated in said spring pockets engage the side frame 1 to resiliently support the locomotive. An oil box 15 adapted to contain a grease packing for the lubrication of the axle journal 8, is securely attached to the journal box 10 by heavy 'attachment bolts 16. semicircular flanges 17 formed integral with the journal lining 9, engage the outer surfaces of the journal box to hold said journal lining in operative position. A semicircular plate 18 composed of antifriction metal similar to that of the journal lining 9, cooperates with the flange 17 to form a circular thrust bearing against which the hub 19 of the driving wheel 5 bears to limit longitudinal movement of the axle 7 relative to the side frame 1. Lugs 5D (ma 20 formed on the inner face of the semicircular plate 18 extend longitudinally of the axle and have at their inner ends flanges 21 which engage the end walls 22 of the oil box to. hold the plates 18 in operative position. A projection 23 formed in the end wall 22 of the oil box extends between the lugs 20 to prevent rotary movement of the bearing plate 18 about the axle journal 7 As heretofore constructed journal boxes of the class described have been provided with end thrust bearings positioned above the axle bearings and extending little more than half way around the axle. Such bearings are objectionable because the unbalanced pressure of the thrust bearings against the wheel hub causes excessive wear upon the contacting surfaces. By my improved construction the thrust bearing extends entirely around the axle, insuring a fair bearing against the wheel hub, and greatly reducing the wear upon the contao ing surfaces. When the flanges 17 and the bearing plates 18 become worn in service, the oil box 15 may be removed by the withdrawal of the bolts 16, after which the worn parts may be easily removed and new ones substituted. Because of the symmetrical form of the bearing lining 9 and the oil box 15, these parts may be turned end for end to supply new thrust bearing flanges 17 and 18 thus doubling the life of the bearings.

What I claim is 1. In a bearing of the class described, the combination with a journal box having a removable antifriction metal journal lining, an axle having a journal bearing upon said lining, an oil box secured to said journal box below said axle journal, and an antifriction metal plate attached to said oil box and cooperating with a flange of said linings to form a thrust bearing adapted to engage a member on said axle to limit its longitudinal movement relative to the journal box.

2. In a bearing of the class described, the combination with a journal box having a removable antiiriction metal ournal lining, an axle having a journal bearing upon said lining, an oil box secured to said journal. box below said axle journal, and a semicircular antifriction metal bearing plate attached to said oil box and cooperating with a semicircular flange on said lining to form a thrust bearing adapted to engagement with a member on said axle to limit its longitudinal movement relative to the journal box.

3. In a bearing of the class described, the combination with a journal box having a rei'novable antifriction metal journal lining, an axle having a ournal bearing upon said lining, an oil box secured to said journal box below said axle journal and a semicircular antifriction metal plate having lugs adapted to engage the end walls of said oil box to hold said plate in position to cooperatev with a semicircular flange on said lining to form a thrust bearing adapted to enga ement with a member on said axle '3 bearing adapted to engagement with a member on said axle to limit its longitudinal movement relative to the journal box. In testimony whereof I have hereunto set my hand.
